W1 TNESSES To all., ivhom it may concern:

' Be it known that T, JOHNJ. BROWN, a-

' citizen of .the United States, residing at -Martins Mills, inthe-county of .Van Zandt vand State of Texas, have invented certain newand u"seful Improvements in'Nut- Locks;

fandI do hereby declare the following to be a full, clear, and exactdescription ofthe invention, suoli as will enable others skilled in theart to which it appertains to make and use-the saine.

This invention relates to new and useful improvements in nut locksA andit is primarily an object of the invention to provide novel device ofthis character engaging the. sides of the nut -to be held againstrotation.

' It is also an object of the invention to f provide a novel device ofthis character wherein` are employed a series of washers adapted to beinterlocked, one of said washers engaging a surface of an articlethrough which the co-active bolt passes while a second washer engagesthe sides of the nut engaging the bolt'.

It is also an object of theinvention-to pro- .vide a novel device ofthislcharacter which will besimple in construction, eliicient and and inwhich,

. junction with the invention.

advantageous in practice and comparatively` inexpensive to manufacture.

With the above and other objects in'view, the invention consists of thedetails of construction and in the novel arrangement and combination ofparts to be hereinafter more.

particularly referred to.

I-n'describing the invention in detail, refereiice will be had to theaccompanying drawings formingpart ofthis speciicatim wherein likecharacters of reference denote corresponding parts in the several views,

Figure 1 is a view in perspective illustrating the invention in appliedposition. Fig. 2 is aview partly in section-and partly in plan of one ofthewashers employed in conl i of a washer surrounding the bolt beneathFig. 3 is a view in bottom plan of the washer shown in washer employedin the invention.

Tn the drawings, 1 denotes a bolt of any ordinary or preferredconstruction which is adapted to be engaged by the nut 2 angular incross section. j

Before the nut 2 is applied to the bolt 1,

said bolt is surrounded by a washer 3 having Specification of LettersPatenti *y Application ined my 7,71908. serial No. 442,336.

This engagemel-te r the lug 4 will hold the Washer. 3i against'rotation has projecting upwardly from its face opposed to the nut'2when applied and positioned at opposed points thereon, the..

broad lugs 8 between which the nut 2 is adapted to snugly lit. Theopposed faces of the washers 43) and 7 are provided with radiallydisposed recesses 9 and 10, respectively,

adapted to register one with the other and extending inwardly" from theperipheries of the washers.

The recesses 10' within the therearound While the washer 3" has a lim--vEach of the recesses terminates in an enlarged'approximately circular4portion 11. washer 7 are arranged lat intervals entirely:`

ited number of recesses, in this' instance shown as two and arranged at'distances apart of about one-fourth of the washer. When certain of these`recesses 9 and 10 are in register there is inserted therein the splitlocking pin 12, said pinbeing of such thickness as to contact withthelwalls of both of the recesses- 9and 10. AThe inner end of this pinis provided with outwardly projecting segmental lugs 13``vhich, owing tothe -natural resiliency possessed by the split shank ofthe pin, willextend within the enlarged portions 11 of the recesses and be heldeffectually against accidental displacement.

Therefore, it will be seen that the pin 12.- locks the washer 7 and thewasher 3 and as the washer 3 is held against movement i through themedium of the lug 4, the broad lugs 8 of the washer 7 enga ing opposedsides of the nut 2 will lock said nut to the bolt l.

I claim: l

1. .In combination with a bolt and its nut;

fioo

wardly from the peripheries of the washers,

said recesses terminating at their lower ends in circular portions', apin insertible within certain of the recesses of the washers when inregister, said pins having outwardly projeeting lgs at their lower ends,curved to fit the circular ortion ai; the lcwerends of the recesses, anmeans carried by' the second named washer ceA engage the sides ofthenut.

'2. In combination with a. bolt and its nut; of a Washer surrounding thebolt beneath the nut, a lug projecting from the outer surface of thewasher, a second washer surrounding the bolt above the irst namedWasher, the oposed faces of the Washers being provide with radialrecesses 'having their inner ends enlarged and' formed substantiallycircular in cross section a pin insertible Within certain of `cherecesses when in register, said pin being split and havingv V outwardlyextending lugs to t Witlin th?` enlarged portions' of the recesses, saidlugs beingA curved to lit the enlarged inner ends of the recesses, andmeans carried by the sec- A :3nd named Washer to engage the sides of thenut.

In.;testimony whereof I have signed 'my name to this specification inthe presence of two subscribing witnesses.
